I rode the XO-2 on at the Virginia Beach Boardwalk yesterday morning. 3 1/2 miles from the begining to the other end of the boardwalk, or up and back for 7 miles total. Wow what a nice comfortable ride.
It currently has a 3 1/2 inch high rise mountain bar and I actually like it with that. The old Shimano DX top mount thumb Shifters worked great.
